Common > NEW CONTEST! 

Welcome to the new contest - you can prove your mathematical abilities or just to have some fun; you can also earn some money and to improve your financial situation for a bit...For those, who dare!

The only thing you need to do is to read the task very intently, to find the answer and to send it to the next e-mail: MiladyWinter@hot.ee
Please, do not post your answers to the forum - after the deadline (July, the 21th, 21:00 servet time) all answers will be posted by paladin to the forum and all people will get to know the right answer and the name of the winner.

Here is the task:
Low Power, Milady Winter and Smile of Rain were waiting for a bus - they
had spent almost half of the day in the zoo and now they were too tired to
go on foot..Finally, bus came, they had entered and took their tickets..
Milady Winter ticket`s number was 524127. She had stared at the numbers
and smiled after a moment - it was something amazing! She was able to have
number 100 in sum, without changing ticket`s consecution of numbers - just
with help of some mathematical operations.Smile of Rain and Low Power didn`t understand this strange smile..Can you
help them to open the secret of Milady`s smile? How was she able to have
100 in sum?

Good luck, brave hearts!

In your e-mails, please, give the name of your character too :idea: I need to know, who had sent me a letter! It is very important!

Mathematical operations should be SIMPLE!

(5/2x4)x(1+2+7)=100

5*2*((4+1)-(2-7))=100

answers: (5/2*4)*(1+2+7)=10*10=100 is right, but Bandit m was first
                            (5*(1+2+7)=10*10=100 is right and the grant is 1,5 cr

                             4)  
First bracket is supposed to be 3th floor fraction. Grant is for originality

answers: (5*2) * (4+1-2+7) = 100 is right and the grant is 1 cr
                           (5*(-2)) * (-4-1+2-7) = 100 is right and the grant is 0,5cr
                           (-5 *2) * (-4-1+2-7) = 100 is right and the grant is 0,5 cr
                          "And now some diferent 5*2 = 10 and  -4-1-2+7 = 0 so  if we put that 0 in end of 10 we get 100  :)) " ->It is nice answer, but it is not acceptable in this contest, because you need to have 100 in sum by mathematical operations..But logic is very nice!

answer: "left to right got close. right to left: 524127   7+2+1*4/2*5=100"

is wrong -> task asked not to change ticket`s consecution of numbers. Only left to right order was allowed

                           5 *4*1   =25*4*1=100*1=100 Well, it is NOT SIMPLE, as it was needed, but your grant is 1,5 cr for originality.
                     (5/2x4)x(1+2+7)=100  is right, but Bandit m [8] was first
